What Is The Melting And Boiling Point Of Sodium Sulfide?

The melting point of sodium sulfide (Na2S) is 1,176 degrees Celsius, or 2,149 degrees Fahrenheit. The boiling point of sodium sulfide is not well-defined due to its tendency to undergo thermal decomposition when heated. However, it typically decomposes at temperatures above 900 degrees Celsius, or 1,650 degrees Fahrenheit, releasing hydrogen sulfide gas (H2S).
